Good as Z3F and WCY were, they're only at best as good as a single Great each.

GWM will tie up one and the "XF owners" did own XF (Great level at the very least).

talk about underestimating those 2 granddaddy masters who are also martial arts geniuses btw coming up with a lot of wicked kung-fu...both of them are higher than a great no doubt. if GWM was to tie one however, that will most likely be WCY cuz Z3F will beat GWM. and Z3F > XF. sorry to say but its the truth. hAHAHahah according to my books anyways. subjective truth but the truth nonetheless.

Right. Yet Z3F himself said that he might not have achieved the level of the great masters of the past like GJ or YG.

And this is the 100+ year old Z3F. Even if you give a generous dose of modesty, Z3F wouldn't be that much better than a ROCH Great.

as usual, he's just being his humble, modest self. he's certainly up there with GJ and YG. WCY is following very close behind. had it been GJ and YG versus the same team, would u have sided differently?

Actually, I think Z3F was unsure whether Tai Chi Sword, which he had just newly created and not yet tested could beat Ah 3. This is quite reasonable since theory and practice are not the same. It is clear that Z3F is very aware of this.

Guo Jing is supremely good at handling multiple opponents. Golden Wheel Monk + 3 warriors were not able to overcome him.

Guo Jing would be able to handle GWM + 1 other guy at least (let's say Ding Chunqiu).

If Yang Guo busts out Heavy Iron Sword, You Tanzhi + Murong Fu might not be a match for him.

GJ being able to handle multiple opponents was mainly thanks to the Big Dipper Formation as mentioned in the novel. With the granddaddy formation creator, WCY, in this battle, i believe he can also "handle" one of the stronger opponents (YTZ/GWM) and a small potato (DCQ/MRF). While Z3F does his best on the other 2, whoever they are, and eventually edge them out. but thats just me as usual, , ever since JY said that Z3F was the best martial artist in his novels, i just became a strong supporter of Z3F kicking butt in most reasonable match-ups.

Going on further on my rant, both of these granddaddy masters are battle geniuses with plenty of experience, if this fight was drawn out beyond 400 moves, the 2 of them will be able to detect and exploit any weaknesses the other 4 has. Thus, granddaddy masters FTW.

Which means he is extremely fast. When Wang Chongyang learned 9 Yin, he was extremely old. I doubt that his form can be as versatile as mid 30s Guo Jing.

It's this.兼之他在掌法之中杂以全真教天罡北斗阵的阵法，斗到分际，身形穿插来去，一个人竟似化身为七人一般

He was able to use Dipper Formation and seem like 7 persons. Though WCY is a bit weaker than GJ, but he is still a Great level and I don't see why he can't use the Dipper Formation like how GJ used it.
I'm not sure of who would win, but at least in comprehension of arts, these 2 are the lords.
